PURPOSES : Sprinkler facilities play a crucial role in extinguishing fires in the early stages of a building blaze. Data indicate that more than 96% of fires are suppressed by sprinklers before growing out of control. However, corrosion and pitting of the sprinkler piping can reduce system performance as facilities age. The purpose of this study is to develop an eco-friendly water-soluble corrosion inhibitor to improve the reliability and longevity of sprinkler piping. METHODS : This study compared and analyzed silicate-based sprinkler piping shrinkage agents as corrosion inhibitor against existing commercial options. Tests were conducted to evaluate reactivity with fire extinguishing water, including electrolyzed reduced water and normal water. The anticorrosive performance of the silicate-based corrosion inhibitor was evaluated under various conditions to establish suitability before potential development or commercialization. RESULTS : The new corrosion inhibitor demonstrated eco-friendly performance. In testing, none of the primary four hazardous substances that pose the most risk of harm to the human body (specifically, arsenic (As), lead (Pb), cadmium (Cd), and mercury (Hg)) were detected. The inhibitor effectively reduced corrosion of carbon steel (SPP), with weight loss rates averaging 0.12% and not exceeding 0.27%. For copper (CDA 110) weight loss rates were up to 0.03%. Testing under constant temperature and humidity conditions show that the inhibitor kept weight loss was below 0.002 g, with no significant numerical value for the weight loss rate. Overall, the results indicate the potential for an environmentally-safe corrosion inhibitor. CONCLUSIONS : The optimal silicate-based sprinkler system can provide real-time sensor information such as oxygen saturation, pH concentration, and total dissolved solids (TDS). These metrics are closely related to the aging process. By linking this system with an aging monitoring solution, maintenance costs and safety could be improved over the lifespan of the sprinkler system. The sensors and monitoring capabilities are expected to enhance maintenance efficiency and equipment reliability.
